I wouldn't worry about them cracking. I've already fkn peened them off rocks and stumps at speed and had no ill effects. Actually, I'd be more worried about aluminum rims cracking in the cold!!! Also, if you do have an issue with them, HiPer has top notch customer service.
Thanks. I thought they would be fine but just was curious. Hey let me ask you is tightening them to torque specs time consuming or what. Star pattern a little at time. Damn I think it took me an hour and a half to do all four. But it is sweet mounting them on your own. :thumbsup: $$ in my pocket.
Yeah, torquing them the first time sucked. It took so much fkn time, I started using and electric impact wrench and hit them in an alternate and equal tighening pattern for a second two, two times per bead. The third time, I bring them home with an the torque wrench.
